Answer:
p(b = 1) = 0.4096 = 40.96%
Step-by-step explanation:
For each candy, there are only two possible outcomes. Either it is blue, or it is not. The probability of a candy being blue is independent of any other candy. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
20% are blue
This means that [tex]p = 0.2[/tex]
Sample of 4
This means that [tex]n = 4[/tex].
Which of the following would find p(b=1)?
P(X = 1). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{4,1}.(0.2)^{1}.(0.8)^{3} = 0.4096[/tex]
So, p(b = 1) = 0.4096 = 40.96%

Does the quadratic function
y = 3x2 + 7x - 8
have one, two or no real zeros?
Utilize the quadratic formula to
determine the answer.
[?] real zeros
Answer:
Two real roots
Step-by-step explanation:
The portion of the quadratic formula that determines the number of roots is
b² - 4ac
If it's positve there are two real roots
If it's zero there is one real root
If it's negative there are no real roots
------------------------------
b² - 4ac = 7² - 4(3)(-8)
b² - 4ac = 49 + 96
b² - 4ac = 145
Two real roots since 145 is positive
The quadratic equation has two real zeroes
What is quadratic equations?
The polynomial equations of degree two in one variable of type f(x) = ax2 + bx + c = 0 and with a, b, c, and R R and a 0 are known as quadratic equations. It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" for the absolute term of f. (x). The roots of the quadratic equation are the values of x that fulfill the equation (, ).
It is a given that the quadratic equation has two roots. Roots might have either a real or imaginary nature.
What is quadratic formlua?
D=b²-4ac
x=(-b±√(b²-4ac))/2a
y = 3x² + 7x - 8
On comparing with ax²+bx+c, we get
a=3, b=7 and c=-8
Using Quadratic formula
D=b²-4ac
=7²+4x3x8
=49+96
=145>0
Hence it has real zeroes

Required:
a. Change the variable names to Bird Size and Bird Behavior
b. Make a scatter plot.
c. Compute the correlation
Answer:

The area of a rectangle is 70 square feet. The length is 10 feet. Find the width [W] of the rectangle
pls help
W = ___ ____
Answer:
35
Step-by-step explanation:
The answer might be 7 i don't know
Answer:
w = 7 feet
Step-by-step explanation:
The area of the rectangle, 70 ft², is equal to the length, 10 ft, times the width, w.
So, to find w, we can divide the area by the length.
w = 70 / 10
w = 7
The width is equal to 7 feet.
We can check this by multiplying the given length by the width that we've calculated to see if the area is equal to 70 feet².
10 · 7 = A
70 = A
Because the area we found is equal to the given area, our calculations are correct.
I hope this helps ^^

HELP DUE TUESDAY (last day of school)
please solve for x and y in the diagrams below:
x = 10°
y = 112°
Step-by-step explanation:
From the definition of supplementary angles,
68° + y = 180° ---> y = 180° - 68° = 112°
From the definition of vertical angles,
(4x - 2) + 30 = 68
4x - 2 = 68 - 30 = 38
4x = 40
x = 10
Answer:
y+68=180(being straight angle)
y=180-68
y=112
4x-2=30
4x=28
x=7

The answer is D because a circle has at least a 360 degree and a 180 is a half circle.
Find the missing value in the proportion 12/34 = 18/m.
Both the top and bottom numbers would have the same scale (ratio) in order to be a proportion.
Find the scale of the top numbers:
18/12 = 1.5
The top numbers have a scale of 1.5 so the bottom numbers also have a scale of 1.5
Multiply the known bottom number by the scale:
M = 34 x 1.5 = 51
Step-by-step explanation:
[tex] \frac{12}{34} = \frac{18}{m} \\ cross \: multiply \\ 12m = 612 \\ m = \frac{612}{12} \\ m = 51[/tex]

1.)
To get a difference of 0:
{(2,2) ; (3,3)} = 2
Total possible outcomes = sample space = 15
P(difference of 0) = 2 / 15
2.)
Product of 2 resulting numbers is odd:
{(1,3) ; (1,5) ; (1,3) ; (1,5) ; (3,3) ; (3,5)} = 6
Total possible outcomes = 15
P(product is odd) = 6 /15
3.)
Product is atleast 12 :
{(3,5) ; (4,3) ; (4,5)} = 3
Total possible outcomes = 15
P(product is atleast 12) = 3/15 = 1/5

Given:
The function is:
[tex]f(x)=-4x^9[/tex]
To find:
The end behaviors of the given function.
Solution:
We have,
[tex]f(x)=-4x^9[/tex]
The leading coefficient is -4 which is a negative value and the degree of the leading coefficient is 9 which is an odd number. So,
[tex]f(x)\to \infty[/tex] as [tex]x\to -\infty[/tex].
[tex]f(x)\to -\infty[/tex] as [tex]x\to \infty[/tex].
Hence, as [tex]x\to -\infty[/tex], [tex]f(x)\to \infty[/tex] and as [tex]x\to \infty[/tex], [tex]f(x)\to -\infty[/tex].
